To all whom t may concern.-

Be it known that I, ARTHUR E. HULL, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Car-Windows, of whichfthe following is a My object is to provide an improved window construction vadapted more lespecially for passenger-cars and which while being easy to Open 'and close shall be free from vdanger of sticking or rattling.A

It is also my object to render the construction weather and dust proof and capable of firmly supporting the sash at any elevation when opened.

. In carrying out my invention I prefer to provide the opposite edges of the window-sash with metal shoes sliding against metal jambstrips set into the window-casing, the shoes being shaped to form 'retaining 'and housing means for yielding rattling-preventinglocking mechanism, as well as for dust-excluding weather-strips.

Referring to the drawings, Figure 1 =is a broken vertical section, on irregularv line 1in Fig. 2, of a car-window casing at one edge of a sliding sash, which is shown in broken elevation; Figs. 2 and 8, broken plan sections, on different scales, taken,respectively, on lines 2 and 3 in Fig.'1`; Figa, a broken fragmental view, partly in section and partly in elevation, the section being taken on' line 4 in Fig. 1; and Fig. 5, a horizontalsection through a shoe and jamb-strip at one side of the casing and illustrating a modified construction of sash gripping or locking means.

The opposite vertical edges of the raising and lowering sash A are shod with metal `strips B, each formed with lianges a landa 'rib 0, extending the full length of the shoe or strip B and Asash and shaped as shown. The liange a overlaps the outer surface of the sash, and the flange and rib o form between them a retaining-socket for an edge of a flexible weather-strip C, of rubber, canvas, or the like.

Countersunk in the window-casing D at each vertical edge of the sashis a jamb-strip E, preferably of channel form to present the iianges d e'. In the construction shown in Figs. 1, 2, and 3 the Hange 0l Vis provided with a vertical rack f. The outer flange e forms a smooth bearing-surface for the smooth outer surface of the flange portion a b of the shoe B.

Pivotallymounted at their'endsin the sockets g, formed by the rib c, are vertically-swinging links h, pivotally secured at their opposite ends between extension-plates'c' on the upper and lower ends of a bar F. In the construction shown in Figs. 1, 2, and 4 the bar F is provided on-its edge with teeth adapted to engage the teeth ofthe rack f. One or more springs G, mounted' in the sockets g, bear against the straight or'rear edge of the bar F. Pivotally fastened vat its upper end between the lower plate extensionsc' is a depending link H, provided with an opening 7c. A casing or housing I is fastened against the innerface of the sash in the positionv indicated and is formed with an extension or shoulder Z. A

yss

lever K, fulcrumed in the housing I, has an arm extending through an opening in one wall.

.the slot or opening 7c of the link I-I. The

Outer end'portion of the lever K is expanded.

to form athumb-piece or handle m. The bearing-surface a b of the shoe slides readily against the smooth bearing-surface e of the jamb-strip- E,and the weather -strip slides readily upon the surface of the .base of the jamb-strip..l press thebar F rmly against the rack f, binding the sash firmly between the said rack and the surface. e'at each edge of the sash. The engagement of the barsjF with the parts f of the jamb-strips tendrto lock the sash firmly to the casing, thereby preventing movement of the sash and closing the joints between the shoes and surfaces e." e

It will be understood that a casingI and lever K, with attendant parts, are provided near each edge of the sash. When it is desired to raise or lower the sash, the levers K are pressed upward at their handle portions m, thus drawing down the links H land bars F to release the latter from the parts f. Release of the levers K causes the springs Gr' to return the bars F to their normal positions of engagement The springsG tend normally to p IOO groove gripping surfaces inthe modified construction is brought about by movement of the bar F, the same as in the other construction.

The pressure of the bars F prevents all danger of rattling of the sash in its jambs and by pressing the surfaces ab closely against the surfaces e tend to exclude draft and dust. This exclusion is rendered still more certain by the weather-strips C.

While I prefer to provide the sash-locking gripping means described at each edge of the sash, it is within the spirit of my invention to provide the same at one edge only.

The metal shoes and jamb-strips prevent any swelling of the sash or contracting of the frame from causing sticking of the sash, which is one of the principal objections to car-windows as usually provided.

While I prefer to provide the jamb-strips with racksv f to be engaged by movable rackbars F because of the positive gripping they effect, in many cases the construction shown in Fig. 5 may be found preferable, because while the gripping between the bars may not be as effective the V-shaped tongue-andgroove construction tends further to prevent rattling of the sash. If desired, the V-shaped tongue or rib f and the V-shaped groove in the bar F may be Jformed with shallow serrations to render the gripping eiect more positive. f

It will be obvious that where metal sashes A are provided the shoes B may form integral parts thereof.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a car or other window, the combination of a raising and lowering sash provided on its opposite edges with longitudinally-extending metal shoes, longitudinally-extending metal jamb-strips against which the said shoes lit and slide, sash-locking gripping means between companion shoe and jamb-strips, and operating mechanism for Said gripping means.

2. In a car or other window, the combination of a raising and lowering sash provided on its opposite vertical edges with longitudinally-extending metal shoes, longitudinallyextending metal jamb-strips against which the said shoes fit and slide, sash-locking grippingmeans, and weather-stripping between companion shoe and jamb-strips, and operating mechanism for said gripping means.

3. In a car or other window, the combination of a raising and lowering sash provided on its opposite vertical edges with longitudinally-extending metal shoes, longitudinallyextending metal jamb-strips against which the said shoes fit and slide, spring-pressed sashlocking gripping means between companion shoe and jamb-strips, and an operating-lever for said gripping means on the sash.

4. In a car or other window, the combination of a raising and lowering sash provided on its opposite vertical edges with longitudinally-extending metal shoes, longitudinallyextending metal jam b-strips against which the said shoes fit and slide, companion slice and jamb-strips being provided with sash-locking gripping means comprising a stationary rack on one and a movable spring-pressed rack on the other, and operating mechanism for said gripping means.

5. In a car or other window, the combination of a raising and lowering sash provided on its opposite vertical edges with longitudinally-extending metal shoes, longitudinallyextending metal jamb-strips against which the said shoes fit and slide, companion slice and jamb-strips being provided with sash-locking gripping means comprising a stationary rack on the jamb-strip and a movable sp1-ingpressed rack-bar on the sash, and an operating-lever for said rack-bar on the sash.
